the crahke riclofthe'ma-chihfl F1gure 10 1s an elci ationof the filler block 94. Y i t In tefms'cfbr'cad inclusion the slicing chine of my invention ccrhpri'sc ya: suitably with Whichitmay be rotated"; and a" pusher slice as; the loaf or y by tliei less than a right angle to each other, and long enough to receive the largest loaf or bar which it is desired to slice. -At each end of the trough the side 4 is provided with heavy flanges 6 and 7, in which are journaled the feed screw 8, and the drive shaft 9.

Slidably and pivotally mounted on the shaft 9, is arm 10, on the end ofwhich is formed a pusher or late 11 ads. oted to lie in l l a the. trough, as best shown in Figure 8, or to be swung backwardly out of the trough by the handle 12. The arm 10 is also provided with a fractional nut 13, adapted to engage the feed screw 8 when the pusher is in the trough, and to be disengaged from the feed screw, when the-pusher is swung out of the trough. When the nut 13 is disengaged from the feed screw, the pusher may be moved back and forth on the shaft to position it against the end of the. loaf or bar which is to be sliced.

Means are provided for connecting the feed screw for rotation with the shaft during the desired arc of movement of the latter. During such connection, the pusher is of course being inoved by the feed screw. When not so connected the pusher is at rest. The parts are so arranged thatthe period of rest corresponds to that period during which the slicing means is passing thru the material.

Fixed on thefeed screw is a gear 16, in mesh With the wider gear 17, journaled on the shaft 9. Preferably also, the gear 17 is provided with a hub 18 bearing in the flange 6, and in which hub the shaft 9 is also journaled. Fixed on the end of the shaft is the arm 19, carrying the pivotally mounted dog 21, having at one end a tooth 22 adapted to engage in the teeth of the gear 17, and at the other end having a tail 23, adapted to engage the cams 26 and 27. The dog is fixed rigidly on the pivot pin 28, j ournaledin the arm 19; and a spring 29 interposed between the arm and the pin presses the dog resiliently against the cams. The cam 26 is formed as a flange on the casing 31, fixed by any suitable means on the flange 6, and surrounding the gears 16 and 17. The cam 27 is formed as a flange on the movable casing 32, journaled on the end of the shaft 9, and retained thereon by the nut 33. It will be observed from Figure 2, that cams 26 and 27 are each slightly less than 180 degrees in extent; and from Figure 1 it will be noted that the two cams lie side by side. When the tail of the dog is riding upon either of the cams, the tooth 22 is out of engagement with the gear 17 and the feed screw and pusher are at rest. The end 34 of the fixed cam is so positioned that the dog engages it justprior to the entrance of the cutting device into the material in the trough. This lifts the tooth 22 out of the gear 17 and insures the fixed position of the pusher and material during the cutting operation. The other end 36 of the fixed cam is so positioned that the feedingof the pusher, by rearattan son of the engagement of the tooth 22 with the gear 17, cannot begin until after the slicing operation has been completed.

The casing carrying the cam 27 is rotatable about the axis of the shaft, to position the cam 27 relative to the cam 26. When the cams are side by side over their whole length, the dog tail 23 engages and disengages both cams at the same time. In this adjustment the maximum amount of feed for the pusher is secured, since the tooth 22 is then in en gagement with the gear 17, while the tail of the dog is traveling in the are between the end 36 of the fixed cam and the beginning 34 of the fixed cam.

By rotating the casing 32 in the direction of the arrow 37, Figure 2, the end 38 of the adjustable cam may be positioned at any point between the end 36 and the beginning 34 of the fixed cam; so that after leaving the fixed cam, the dog continues in raised position on the adjustable cam, and the tooth 22 is not permitted to engage the gear 17 until the dog leaves the end 38 of the adjustable cam. In the position of the two cams shown in Figure 2, the maximum extension of the cam is shown; the tail of the dog being out of engagement with the cam and the tooth 22 in engagement with the gear 17 for only a short are of movement of the shaft. This represents the shortest possible feed for the pusher. I have found it desirable to so proportion the parts that this minimum is about one fiftieth of an inch; that is to say, with this setting a slice one fiftieth of an inch thick will be cut.

A spring pressed ball 39 is interposed between'the'casing 32 and the fixed casing 31, and recesses41 in the fixed casing 31 provide the seat in which the ball is resiliently caught when the casing 32 is rotated. Graduations 42 on the casing 32 are arranged in correspondence with the seats 41, so that the particular seat in which the ball is lodged, corresponding to the setting of the cam end 38, is 'evaluatedby the graduation. These gracuations are conveniently numberedconsecutively, beginning at 1; and are registered as desired with afixed mark or point 43 on the fixed housing 31. The increments represented by the graduations are preferably about 1/50 of an inch; and in the substantially 180 degrees of movementof the cam, I find it quite possible to provide for cutting slices varyingby this small amount from the thinnest up to nearly one-half inch.

At the opposite end of the trough from the feed mechanism is arranged the cutting or slicing device, and the crank with which the machine is operated. As best shown in Figure 5, the shaft 9 extends thru a tubular bracket 44, rigidly mounted in the flange 7, projecting downwardly from the side of the trough. Fixed on the end of the shaft is the arm 46, provided with a crank handle 47,

The wire ,49 cuts transversely across the four pleces wlth each revolution of the crank, and leaves the four slices of butter in position on the stacker. Preferably, however, the stacker is removed in the slicing of butter and the-pieces permitted to fall into a pan of ice water. When cheese is to be sliced, the whole slice is usually desired and therefore the frame 86 is lifted out of position, and a filler block 94: inserted in its place. The filler block ismerely to bridge the space otherwise occupied by the subdi-, vider, and is substantially,similartothe two lower sides of the subdividing frame, as shown in Figure 10. I
